Tidak dapat terhubung ke Tomcat meskipun sedang berjalan

Saya sudah mencoba menginstal Apache Tomcat 5.5 dan 6 dalam 2 cara berbeda ( dari sumber dan dengan apt-get ) di Debian 5 dan Debian 6 - tidak berhasil. Server sedang berjalan tetapi saya tidak bisa terhubung.

netstat -a:

Saya juga telah mencoba memaksa Tomcat untuk IP eksternal VPS saya. Saya juga mendapatkan Kesalahan terjadi selama inisialisasi VM Tidak dapat memesan ruang yang cukup untuk tumpukan objek. kesalahan dari waktu ke waktu, tapi saya kira itu bukan masalah karena Tomcat tidak merespons.

Maaf untuk banyak teks - Saya mencoba menjadi informatif. Tolong bantu aku. Terima kasih sebelumnya!

PEMBARUAN Seperti yang dinyatakan dalam jawaban, Tomcat mendengarkan pada port IPv6. Untuk mengubah itu, saya harus menambahkan variabel lingkungan untuk mesin JAVA ke /etc/profilefile

JAVA_OPTS="-Djava.net.preferIPv4Stack=true"
export JAVA_OPTS

... muat ulang file: source /etc/profile

... lalu konfigurasikan main Tomcat Connectordengan mengedit /etc/tomcat5.5/server.xml(dalam kasus saya) dengan cara berikut:

<Connector port="8080" maxHttpHeaderSize="8192"
    maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
    enableLookups="false" redirectPort="8443" acceptCount="100"
    connectionTimeout="20000" disableUploadTimeout="true" address="0.0.0.0" />

Perhatikan address="0.0.0.0"yang memberitahu Tomcat untuk mengikat ke alamat IPv4.

Terima kasih atas waktunya, dan semoga harimu menyenangkan semua orang.

Tomcat tampaknya hanya mendengarkan alamat loopback IPv6 ::1,.

Baunya seperti masalah firewall - coba buka aturan yang relevan di firewall Anda (pertimbangkan untuk membiarkan semuanya masuk / keluar lo, saya belum pernah melihat kasus yang sah untuk membatasi lalu lintas loopback).
